◆ buf

struct buffer fragment::buf

Buffer in which received datagrams are reassembled.

◆ defined

bool fragment::defined

Whether reassembly is currently taking place in this structure.

◆ map

unsigned int fragment::map

Reassembly map for recording which fragments have been received.

A bit array where each bit corresponds to a fragment. A 1 bit in element n means that the fragment n has been received. Needs to have at least MAX_FRAGS bits.
